Adding 2nd house battery

[nothermark]

FWIW a second battery will cost the OP around $150 for the battery and the wires. Probably less. It will fit in the space with no modifications. That will double or more his useful battery capacity. Unless the first battery is old or beat up they will keep him going for several years. If the first battery is that bad a single new battery might be all he needs to comfortably make it through a night of dry camping. Anything more than that gets both interesting and expensive given the space and weight limits of a short C. I'm not saying anybody's advice is bad as such. I am saying some of it is really overkill for the original post. The reason I am bothering to say it is that sometimes we scare off folks who are looking for the $100 fix when we try to sell them the $1000 major upgrade.

As a follow up to the above post, I picked up my 2000 Class C, MH 2 1/2 years ago. It came with one 12 volt house battery of unknown age.

I wanted something easy and inexpensive so I installed 2, 6 volt batteries, wired in series, into one of the storage compartments and tied them to the original, 12 volt battery.

I added a 1000 watt inverter and traveled for 2 summers, mostly in non electric state parks and Flying Js.

We could have lights, watch Sat. TV, for too many hours, run a small fan all night and use my Mr. Coffee, 2 times in the AM, before I got a low voltage warning.

The batteries could still start the generator.
